The apple Yor other Atruit X is impaled on the pin 12, the axis of which is in line with the core of the fruit, in position to be forced onto the hollow receiving spindle22, as liereinafter described.

The spindles 22 and 23 are slidably mount- .ed in the opposite ends 24 and 25 of the spindle arm 26, the hub 2T of which is rotatably mounted on the journal 2S, formed on the superframe 29, integrally formed with the foot piece 3 and bolted to the uprights 8,'to form an open frame, superstruc- 1-1 to form a suitable mounting for the various driving and timing mechanisms. rThe hub 27 is provided with the bevel gear 27', preferably integrally formed thereon and enmeshed with a driving pinion 30, xed on the vertical shaft 31, journaled in a boss formed on the superframe 29;,the gear ratio being two to one. T he disk 32 is fixed on the lower end of the vertical shaft 31 and is provided with the groove 33 (see Fig. 10) formed in the lower side thereof. This groove is engaged by the pins 34 and 34 fixed in the sector 35, that is in turn rotatable upon the stud 36 fixed in the superframe 29. The sector 35 is rotated by the gear 37 enmeshed with the pinion 38 fixed on the end of the shaft 39 journaled in the supertrame 29, and rotated by the driven gear 40 fixed thereon. The gear 40 is rotated by the driving pinion 41, fixed on the-driven shaft 42, journaled in the supertrarne and rotated by the driven gear 43, enmeshed with the driving gear 44 mounted on the shaft 45 adapted to be rotated by the crank fixed thereon, or by a suitable pulley, if the machine is mechanically driven.

The spindle arm 26 is held in the vertical position illustrated by the latch 4T resiliently slidable in the superframe 29, and engaging a depression in the disk 32, to maintain the arm 26 in the desired position during the coring and paring operations. Through the driving mechanism the sector 35 receives a continuous rotary motion carrying the pins 34 and 34 into the slot 33.

Assuming that the part 33 is in the position shown in Fig. 10 and that the pin 34 is approaching the open end of the slot, the pin just mentioned, the pin 34 will be outside of the axis of' the part so that the axis of the shaft 31 will lie between the pin 34 and the axis of the shaft 39. Further rotation of the pin 34 will swing the slotI until it has exactly the reverse position, the pin 34 press- 4ing against` what was previously the outer face of theslot'iarther away'trom the axis of rotation of they pin, `but whichbecomes the inner 'face as soon as the slot passes its `central position. The orbit of the pin 34 engaging the transverse slot causes a half rotation of the disk 32, presents the opposite end of the slot to the entry of the pin 34 to complete the rotation of the disk 32, causes the pinion 30 to make one complete revolution, imparts a one-half revolution to the gear 27 which carries the spindle 22 to the present position of the paring spindle 23. See Figs. 1 and 2. i

rlhese spindles are provided with the collars 48-48 provided with jaws', to engage clutch jaws 49 on the pinions 50, journaled in the arm 26, and held therein by the set screws 51 threaded in the arms and engaging a groove in the hub of the pinions 50. The spindles 22 and 23 are provided with the set collars 52, adjustable thereon and abutting the ends 24 and 25 of the arm L6 to regulate the disengagement of the clutches 48.

The rotation'of the hub 2T by the gear 30, in transposino' the position of the spindles as described, brings the orbit of' the spindles into conjunction with the eccentric orbit ot' the gear wheel 53, fixed upon the shaft 54 rotated by the shaft 42. The conjunction of these orbits brings the pinion 50 into mesh with the gearv 53, causing the rotation of the spindle 23, and the fruit impaled thereon when the clutch is engaged, as hereinafter described. In like manner as one pinion 50 goes into mesh, the similar pinion on the other spindle disengages from the gear 53.

The rotation of the sector 35 carrying the in 55 engaging the cam 56 in the cross head 9, (see Fig. 10), forces the cross head back, withdrawing the plunger 5T 'from the hollow spindle 23 (see Fig. 2). rhe plunger 57 is pivoted on a pin 58 journaled in the arms 59 forming part of the bracket 60` in turn fixed to the guide rods 6 6. The plunger 57 is provided with'the arm 61, having a pin 62 resting in a slot in the bracket 63, extending outward from the side plate 4 of the feed carriage. Then the Vbracket 60 moves backward with the guide rods 6 the arm 61 engages the bracket 63, and tips the plunger downward when .thebracket 60: assumesfthe positionshown in .Y `dotted` lines -Fig..2. The feed--.carriage 4, is

thatzirasfnowpassed th'ercenter, carries :the

Y cross head 9 forward, taking the feed Lear.-

riage 4 and the bracket 60 with it, forcing the plunger 57 into the hollow spindles 23,

carrying' the stirrup 13 away from the pins 18, permitting kthe torsion of the springs 16 to carry the appleX to the horizontal position, to be forcedv on to the sharpened end of the hollow spindle 22, by the forward movementof the feed carriage, as shown in dotted lines Fig. 1.

Theforward movement of the feed car riage carries the paring knife 66. forward into engagement with the now rotating fruit X impaled on the spindle 23, and prevented from rotating thereon by the ns 23. The forward movement of the plunger 57 engaging the core within the spindle 23 forces Y the spindle forward until the clutch 48'engages the clutch in the pinion 50, insuring the positive rotation of the lspindle 23. The continued forward movementl of the carriage 4 brings the vsegmental gear 67 into engagement with the rack bar 21, causing therot'ation ofthe segment 67 from which the knife 66 is suspended by the arm 68. The knife isheld against the peripheryV of the fruit by the tension of the spring 69, contracting between the arm 68 and the end of the pin 70, upon whichv the segment.

67 is centered. The guard 7l bearing against the skin of the fruit ahead ofthe cutting edge, prevents the edge from gouging deeply intothe fruit, causing the blade to remove only the skin of the fruit. The rotation of the segment 67 by the rack 21, causes the knife to describe a circle concentric with the axis of the fruit. The edge of the blade pares the fruit clear up to the circumference of the spindles 23 at both ends, eliminating all necessity 'for hand paring, and finishing.V The fruit needV not bel touched by human hands after being fed to the machine.

To'prevent the blade 66 from gouging into the now completely peeled fruit during the return stroke of the cross head, the arm 68 1s provided with the trip 72, that rides up the incline 73, to the top 74 of the cam 75, fixed on the bracket 76, eXtendingout-y ward from the guide 77 formed on the feeder carriage. During the peeling interval the trip 72 ,does not influence the orbit ofthe knife, butl on the return stroke it drops oft' of the upper face 74 of the cam at 78 and rides back on the flange 7 8, the end the. adjacent sills 1.

Y The tipping downward of the plunger 57 as previously described delivers the .fruit to vawsuitable bin or conveyer beneath the machine.

The clean uncontaminated lfruit is delivered from the machine at one point, the parings at another behind the shield 92, and the cores are successively pushed out of the spindle by the entrance of the plunger 57.

The various machines in the group are synchronized in their operations so as to cometo the feeding position as in Fig'. 2, alternately so that the operator can place the group on the spikes 12 with the least number of motions and physical effort.

rlhe machines are boltedv together by the connecting brackets 93 in which the driving shaft 45 is journaled. (See Fig. 3.) The end of the bracket'93 is bolted to the faced lug 94 of the contiguous machine, the 'driving sprocket 44 enmeshing with the driven sprocket 43 of the companion machines. Any number of machines may be thus joined together and driven` from a single sourcel of power.

Having thus described this invention what I claim and desire to secure by Letters Patent is 1. A paring machine includinga frame; aguide slidable in said frame; acarriage resiliently slidable on said guide; abutments on said frame in the path of said carriage; a mechanism on said carriage; a plurality of spindles mounted upon an arm rotatable on said frame; means for rotating said arm and said spindle;

means for synchronously moving said car- 2. A paring machine including et frame; a guide slidable in said frame; a. carriage mounted on said guide; n feeding and a paring mechanism on said Carriage; an arm rotatable on said frame; a pluiality of spindles on said arm; means for rotating said arm and said spindles; means for alternately holding said spindles in alinement With said feeding and paring mechanism, and n stripper on said carriage synchronized with said 10 paring mechanism.

In testimony whereof I have hereunto signed my name this 22nd day of May, 1915.
